ROCK WOOL INSULATION

Rock wool lightly resin bonded mattresses (LRB) consists of fine fibers spun from selected rocks melted at high temperature and bonded with a thermo setting resin. They are Machine laid fiber lay pattern and are baked to form mattresses of predetermined density and thickness.
Mattresses are then slit and stitched to specified dimensions . It has controlled thickness and density resulting in predictable heat losses.
Shreerock mattresses manufactured from selected rocks to State of the Art Specification fully conform to national and international standards such as IS : 8183 - 1993 BS : 3958 Part - 3 ASTM:C592 - 80.
Application:
LRB mattresses are used for Hot & Cold insulation to conserve energy It is used in the thermal insulation of large vessels, boilers, , equipment, ducts, flanges, valves and plants operating at high temperatures.

Packing:
Shreerock LRB Mattresses are packed in HDPE bags.

ROCKINSUL RB slabs are semi-rigid and rigid boards manufactured from stable rock fibers bonded with a minimum quantity of thermosetting resin binder. ROCKINSUL RB slabs are capable of withstanding extreme temperature up to 750 °C and are light weight, strong, resilient, easy to handle, and easy to cut to suit intricate shapes.STANDARD DIMENSIONSThickness(mm)Width(mm)Length(m)25 to 1256001.0 to 1.2STANDARD DENSITYDensity(kg/m3)Thickness(mm)4850 - 2006440 - 1508040 - 1259625 - 10012025 - 8014425 - 8016025 - 75* Non-standardized sizes and facing may be available on requestFACING TYPESROCKINSUL RB Slabs are available unfaced or with facing of ALG, glass reinforced Aluminium Foil/ Kraft paper laminate facing (FSK), Black Fiber Glass Tissue (BGT)WORKING TEMPERATUREFiber : Up to 750 °CFacing : 100 °CAt temperatures in excess of 230 °C a limited migration of binder may occur in the insulation in contact with the hot face. This does not impair the insulation performance.ACOUSTIC PERFORMANCEROCKINSUL RB Slabs achieve excellent acoustic performances (sound absorption coefficients, sound insulation, and impact sound isolation) when tested in accordance to various relevant ASTM standards. RB Slabs achieve Noise Reduction Coefficient (NRC) values up to 1, when tested in accordance to ASTM C423.FIRE SAFETY PERFORMANCEUnfaced ROCKINSUL RB Slabs are non-combustible when tested in accordance with IS 3144, BS 476 (part 4), ISO 1182 and ASTM E136 and are classified as Class A1, in accordance with European norms. Unfaced, FSK and ALG-faced RB Slabs have the following fire safety rating achievements:Class 1 surface spread of flame in accordance to BS 476 (part 7)Class 0 in accordance to the BS 476 (part 6 & 7) and to British Building Regulations.Surface burning characteristics in accordance to ASTM E84 / UL 723a: Fire Spread Index: Less than 25b: Smoke Developed Index: Less than 50

Rockloyd Slab - Resin Bonded, Rockwool Slabs
Rockloyd is a precisely engineered Resin Bonded Fibrous Insulation to offer maximum resistance to heat passage. Rockloyd Fibres are spun from selected rocks, melted at 1600°c and blended to a carefully adjusted chemical composition. Its centrifugally spun fibres have a diameter 1/20^th that of human hair which are felted using state of art Technology into bonded and cured slabs to optimum density and resilience.
